    When idling you can hear that the engine isnt running smoothly, although when looking at rev counter there is about a 3mm dip sometimes and it may dip to 500rpm then back to just under 1k

    Whats the best thing to do first? Sprayed a blast of carb cleaner into the throttle body but didnt do much.

    Lambda sensor or idle control valve my next port of call?

    mine does this....and ive always thought it was due to the fact that the car hasnt been serviced since its very first time (car has now got 28k on the clock) hasnt had a service since it hit 12k!

    let me know please mate if you do find out what it is....then i can fix mine

    btw....does your engine sometimes shake un-natuarally? mine does this on occations...

    mines doing this except its going down to 500rpm then shotting up to 2000rpm n then coming back and idling at 1000! all totally wrong, i heard its the temperature sensor, not sure how that works but worth a try, only cost few quid, i aint got round to doing it yet

    Ok thanks, is it best to get the idle control valve from citroen or will motor factors such as dingbro stock them?

    My VTR/S conversion does this.. but generally has a rough idle.. I had my mate from garage take a look and he thinks my engine has been cammed.. that I got from breakers yard.. Result..

    Haha.. I think he is wrong.. what are the chances of that.. I'm thinking of changing the ICV..

    When was the last time it was serviced?

    I would check and change the IAC valve, coolant temp tempsor, also the IAT.

    Saxo's don't idle.

    If yours does, it's either got throttle bodies, or *about* to start idling badly

    Check out the smilie, it was a gag - there are daily posts regarding idling problems, and iTB's don't have it because they use air-gap and TPS for fueling and ignition not MAP so Idle is much more stable.

    Saxo's DONT IDLE you said. So what do they do? of course they idle.

    I'm not stressing im just explaining tht RDC- Performance or whatever you call yourself has given me stupid information on two ocasions.

    No harm in that i feel?

    Just expressing my views

    Me writing "Saxo's don't idle" is so clearly a joke "chum", the fact you are taking my obvious joke literally proves you are looking through the post and deciding to pick me up on something in order to deliver a put-down.

    I guess you should look in the for-sale section for a "sense-of-humour"

    (see ^ ^ I did it again - a joke - something that is so obviously not for sale, something you can't buy, I said you should buy it.... it's humour my friend)

    We have always found the saxo idle to be aweful.

    And the fact "ive got bad idle problems" post's pop up nearly on a daily basis has to promote our point.

    Hi people at the mo my car seems to miss idle when a warm engien the car goes from idleing point to a complete drop for 3 secs and its like the cars gonna stall. Ive heard people say its the coil pack that needs changing But not to sure. I did have a dickie temp sensor. It was aking my temp gauge go upto red zone but not warning light or anything like that as soon as i wiggled it it solved the problem but i cant seeing that being the problem for the car to idle like its cold.

    i didn't think a code would show unless your light is on the dash?
    so no light, no point getting a diagnostic test.

    Been told its that too Leeroy, but a scan will not pick up a dodgy ICV.

    What symptoms did Tupps have mate?

    just wouldnt idle sometimes up and down the revs, removed the plug to the idle control valve, gave it a tap plugged it back in idle properly

    honestly thats all it will be, sensors aint much at all, or just removed it and clean it with some carb cleaner

    In all honesty, yer it might be the wrong one lol. Ill put the old one back in it.

    It idles nicer when cold tho lol. It fires straight up. You know the VTS common idle problems, have you come across it before in person and fixed it? If so, whats the thing you fixed/changed?
